A comprehensive study reveals SARS-CoV-2 viral-to-human protein interaction network, showing how the virus hijacks human proteins. Researchers identified 23 candidate drugs, including an FDA-approved beta-blocker that shows promise in inhibiting viral infection.
Researchers at the University of Arizona have identified a protein called Ait1 that regulates cell growth in yeasts. This discovery presents new targets for developing antifungal drugs that can attack disease-causing yeasts while sparing human immune cells.
Researchers identified immune endothelial cells promoting inflammation and developmental endothelial cells supporting cell development, regeneration, and proliferation. The study's findings may lead to targeted treatments for lung infections and acute respiratory distress syndrome.
A new study suggests that growing up with dogs and in large families may lower the risk of inflammatory bowel disease. Exposure to dogs, particularly between ages 5-15, was linked to healthy gut permeability and a balanced immune response, which may help protect against Crohn's disease.
A team of researchers developed a novel chip-based infection model to study invasive aspergillosis, a mold infection that affects the lungs. The model allows for live microscopic observation of damage caused by fungal hyphae and the response of immune cells.
Scientists have identified a new immune process that regulates inflammation in human fat, which may help manage obesity. The research found that specific immune cells can work together in fat tissue to cause weight gain and obesity.
Researchers discovered that Candida albicans stimulates human immune cells to release microRNAs, triggering increased fungal growth. The fungus exploits human immune defenses by releasing signal molecules recognized by special immune cells.
Scientists at Washington State University have discovered a novel theory that the innate immune system can respond differently to specific pathogens. This quality, known as immunological specificity, is driven by the nervous system and could provide a basis for finetuning an experimental treatment to fight infection.
A study published by Arizona State University found that survivors of Hurricane Maria experienced accelerated aging in their immune systems, with molecular changes indicating a 7-8 year acceleration in human lifespan. The research used rhesus macaques as a model to explore the effects of extreme weather events on biological aging.
Antibodies that mimic the SARS-CoV-2 virus may explain lingering symptoms of long-haul COVID-19 and rare vaccine side effects like allergic reactions and blood-clotting. This theory, based on classic immunological concepts, suggests a cascade of immune responses that can lead to adverse effects.
A new AAV-delivered gene therapy strategy uses immunomodulation to reduce inflammation and improve efficacy. By incorporating TLR9-inhibitory sequences into the AAV genome, researchers have enhanced expression of transgenes in mice, suggesting potential for higher efficacy.
Dr. Anthony Fauci is being recognized for his significant contributions to science and medicine, particularly in the fields of immunology and infectious diseases. He has made numerous groundbreaking research discoveries and has been a key figure in shaping public policy during the COVID-19 pandemic.
Researchers at UCalgary's Snyder Institute for Chronic Diseases have unlocked new insights into the regulation of immunity against chronic infectious diseases. The study found that immune responses thought to be non-protective are actually essential in regulating excessive inflammation, which can facilitate infection.
Researchers have isolated specific cells that can target rogue immune T-cells, potentially rebooting the immune system. This 'antigen-specific immunotherapy' shows promise in treating existing inflammatory autoimmune diseases.
Scientists have created a retroviral CRISPR-Cas9 gene editing library to explore the regulation of mouse T cells, mapping the most important genes for controlling T helper cells and identifying several new regulatory genes. This could help develop new treatments to activate the immune system.
Researchers at Helmholtz Munich have discovered a new cofactor, NUFIP2, that works with Roquin to regulate the immune response. This cooperative regulation helps limit immune responses to specific reactions and prevents inflammatory reactions.
Researchers have made a breakthrough in treating autoimmune diabetes using genetically modified gut bacteria, increasing the frequency of cured mice compared to traditional methods. The new approach has no adverse side effects and allows the immune system to function normally.
A new study found that growing up on a farm increases regulatory T-lymphocytes, cells that damp down the immune system and limit immune responses. This shift in cell ratio is associated with reduced antibody responses to food proteins and lower risk of allergies.
Researchers at Goethe University Frankfurt have elucidated a new signaling pathway in the immune system that regulates inflammation and chronic dermatitis. The discovery provides new avenues for therapeutic intervention and potential targeted therapy for patients with unclear origin.
Scientists at Goethe University report a paradigm shift in immune response regulation, revealing the crucial role of linear ubiquitin chains in nuclear factor kappa B activation. This finding may lead to structure-based drug design for targeting the NF-κB pathway in diseases such as cancer and inflammation.
A double-blind study found that immunomodulation therapy reduced the risk of death from any cause or subsequent first hospitalisation for cardiovascular reasons by 8%. In subgroups with no history of heart attack, IMT was associated with a 26% reduction in primary events.
Researchers developed a novel assay to examine T cell responses to autoantigens in islet cells, revealing distinct pathways of T cell differentiation and maturation in normal individuals versus patients with T1DM. These findings suggest proinflammatory polarization in diabetes but regulatory phenotypes in health.
Dr. Anthony S. Fauci has been recognized for his significant contributions to understanding the regulation of the human immune response and the pathogenesis of HIV disease. He has developed effective therapies for formerly fatal diseases and has pioneered strategies for therapy and immune reconstitution of patients with AIDS.
Researchers found that perforin, crucial for destroying abnormal cells, also plays a regulatory role in controlling the immune system's response to infections. This discovery may lead to new treatments and cures for diseases like lupus and multiple sclerosis.
